Reaction Steps

To 3-({1-[(6-amino-1H-pyrazolo[3,4-b]pyridin-3-yl)methyl]-5-chloro-1H-indazol-4-yl}oxy)-5-chlorobenzonitrile (0.936 g, 2.079 mmol) as a solution in 20% methanol in chloroform (300 mL) was added 1N HCl (2.079 mL, 2.079 mmol), and the resulting mixture was then concentrated under reduced pressure. The resulting white paste was diluted with acetonitrile (100 mL) and the solvent evaporated in vacuo. The dilution-evaporation was repeated twice more for a total of three times. The resulting residue was placed under vacuum overnight to give product. 1H NMR (DMSO-d6): 6.7.91 (s, 1H), 7.81 (s, 3H), 7.68-7.60 (m, 2H), 7.48 (s, 1H), 7.37 (s, 1H), 6.50-6.30 (m, 2H), 6.00-5.86 (m, 2H). HRMS (M+1)=450.06
